Bullitt didn't mention specifics as to what's led to the 180, but reports out of spring practice in Lubbock suggest the Red Raiders have seen a spike in morale and energy since newly hired head coach Kliff Kingsbury took over for Tommy Tuberville.

But Bullitt has also dealt with his own injury issues over the past two seasons that have limited him. Bullitt injured his shoulder during fall camp before the 2011 season and played through the pain all year before having surgery in the off-season. Bullitt reinjured the shoulder last season and eventually had to undergo a second surgery, ending his year early.

Despite his injury problems, Bullitt has earned All-Big 12 honorable mention honors each of the last two seasons.
